For the diversity of industrial flow measurement instruments, such as turbine flow meters and vortex flow meters, which are often mistaken by companies, what is the difference between them?

 

1. Differences in application areas

 

Vortex flow meter: It is mainly used for flow measurement of medium and fluid in industrial pipelines, such as gas, liquid, steam and other media. It is characterized by small pressure loss, large measuring range, high precision, and is almost not affected by parameters such as fluid density, pressure, temperature, viscosity, etc. when measuring the volume flow of the working condition. No moving mechanical parts, so high reliability and low maintenance. Instrument parameters can be stable for a long time.

 

Turbine flow meter: widely used in the following measurement objects: petroleum, organic liquids, inorganic liquids, liquefied gas, natural gas, coal gas and cryogenic fluids and other aspects. It has the advantages of simple structure, few processing parts, light weight, convenient maintenance, large flow capacity (large flow through the same caliber) and adaptable to high parameters (high temperature, high pressure and low temperature).

 

Second, the difference between production and manufacturing
 

 

A turbine flowmeter is an instrument that uses a multi-blade rotor (turbine) to measure the average flow of a fluid and calculate flow or total flow from it.

 

The vortex flowmeter is designed and manufactured according to the principle of Karman vortex. The flow rate is measured using the principle of fluid oscillation. When the fluid passes through the vortex transmitter in the pipe, the triangular column vortex generator alternately generates two rows of vortices in proportion to the flow. The release frequency of the vortex generator is related to the average velocity of the fluid flowing through the vortex generator and the characteristics of the vortex generator

 

3. Differences in data transmission

 

The turbine flow meter cuts off the magnetic induction line through the rotation of the impeller, and then measures the output flow through signal processing.

 

Vortex flowmeter is a flow measurement method that processes the output signal by detecting the Karman vortex.
